Tricuspid Valve S-Curves and Chamber Views: Implications for Transcatheter Tricuspid and Pulmonary Valve Interventions, Part 2 of the S-Curves and Chamber Views Series.

Despite the challenges associated with periprocedural imaging, transcatheter tricuspid valve interventions have shown important impact on outcomes. A comprehensive understanding of the anatomy of the right heart and surrounding structures is crucial. One way to optimize these interventions is by identifying the optimal fluoroscopic viewing angles along the S-curve of the tricuspid valve.

Lipoprotein (a) Testing in Patients With Atherosclerotic Cardiovascular Disease in 5 Large US Health Systems.

Background: Lipoprotein (a) is an independent risk factor for atherosclerotic cardiovascular disease. However, lipoprotein (a) testing remains variable and it is unclear what factors influence testing and if testing changes clinical management.

Methods And Results: A retrospective study using electronic medical record data from 5 health systems identified an atherosclerotic cardiovascular disease cohort divided into those with and without a lipoprotein (a) test between 2019 and 2021.

Real-world exploration of LDL-cholesterol management in patients with atherosclerotic cardiovascular disease.

Background: Although guidelines recommend low-density lipoprotein cholesterol (LDL-C) to be < 70 mg/dL in patients with atherosclerotic cardiovascular disease (ASCVD), the rate of achieving this goal remains suboptimal. We sought to understand real world contemporary practice patterns of LDL-C management in patients with ASCVD, and whether LDL-C testing influenced management across US health systems.

Methods: A retrospective cohort study utilizing electronic medical record data from five health systems participating in the CardioHealth Alliance was performed on patients with an LDL-C measurement in 2021 and prior ASCVD.

An International, Expert-Based Delphi Consensus Document on Controversial Issues about TransCarotid Artery Revascularization (TCAR).

Background: Transcarotid artery revascularization (TCAR) has emerged as an alternative therapeutic modality to carotid endarterectomy (CEA) and transfemoral carotid artery stenting (TFCAS) for the management of patients with carotid artery stenosis. However, certain issues regarding the indications and contraindications of TCAR remain unanswered or unresolved. The aim of this international, expert-based Delphi consensus document was to attempt to provide some guidance on these topics.

Pericardial Diseases: International Position Statement on New Concepts and Advances in Multimodality Cardiac Imaging.

Pericardial diseases have gained renewed clinical interest, leading to a renaissance in the field. There have been many recent advances in pericardial diseases in both multimodality cardiac imaging of diagnoses, such as recurrent, transient constrictive and effusive-constrictive pericarditis, and targeted therapeutics, especially anti-interleukin (IL)-1 agents that affect the inflammasome as part of autoinflammatory pathophysiology. There remains a large educational gap for clinicians, leading to variability in evaluation and management of these patients.

Routine Versus Selective Distal Perfusion Catheter Use in Venoarterial Extracorporeal Membrane Oxygenation.

Although current studies support the use of prophylactic distal perfusion catheters (DPCs) to decrease limb ischemia in patients on venoarterial extracorporeal membrane oxygenation (VA ECMO), methods for monitoring limb ischemia differ between studies. We evaluated the safety of a selective rather than prophylactic DPC strategy at a single center with a well-established protocol for limb ischemia monitoring. Distal perfusion catheters were placed selectively if there was evidence of hypoperfusion at any point until decannulation.

Tricuspid Valve Leaflets-Lead Interaction: Adjunctive Role of Functional Cardiac Computed Tomography for Clinical Decision Making.

The diagnostic approach toward the management of cardiac implantable electronic device-related tricuspid regurgitation is challenging and undefined. Functional cardiac computed tomography angiography provides a complementary role to echocardiography in the evaluation of lead-leaflet interaction which can help the clinical decision-making process, as presented in this case series.

Clinical Trial Inclusion and Impact on Early Adoption of Medical Innovation in Diverse Populations.

Background: Inadequate inclusion in clinical trial enrollment may contribute to health inequities by evaluating interventions in cohorts that do not fully represent target populations.

Objectives: The aim of this study was to determine if characteristics of patients with heart failure (HF) enrolled in a pivotal trial are associated with who receives an intervention after approval.

Methods: Demographics from 2,017,107 Medicare patients hospitalized for HF were compared with those of the first 10,631 Medicare beneficiaries who received implantable pulmonary artery pressure sensors.

Early vs. delayed mechanical circulatory support in patients with acute myocardial infarction and cardiogenic shock.

Aims: Despite increased temporary mechanical circulatory support (tMCS) utilization for acute myocardial infarction complicated by cardiogenic shock (AMI-CS), data regarding efficacy and optimal timing for tMCS support are limited. This study aimed to describe outcomes based on tMCS timing in AMI-CS and to identify predictors of 30-day mortality and readmission.

Methods And Results: Patients with AMI-CS identified in the National Readmissions Database were grouped according to the use of tMCS and early (<24 h) vs.

Self-Apposing Stents in Coronary Chronic Total Occlusions: A Pilot Study.

Objectives: This pilot study assessed the 12-month angiographic and clinical outcomes of self-apposing (SA) stents in patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Background: Self-apposing (SA) stents may decrease incomplete strut apposition and stent strut coverage that are common after CTO PCI.

Methods: We compared 20 patients who underwent CTO PCI using SA drug-eluting stents (DESs) with 20 matched control patients who underwent CTO PCI using balloon-expandable (BE)-DESs.
